Hello list,
As anyone been able to run a webcam on a verdex with the gspca driver
and if yes, with which version ? I am running revision 1431 of the
buildroot and I have the same version of the linux kernel (2.6.21) and
the gspca driver version 08/05/2007 on my desktop computer, but the
driver fails on the verdex with a reference to a NULL pointer and the
more ISOC data error. The error happens with 2 different webcams.
I see that Pascal in a mail from April did manage to with a webcam
supported by gspca.
Thanks,
Regards,
Benjamin

Hello,
I am trying to get a webcam to work on a gumstix board.
Currently I am using Gumstix Board Verdex XM4 with a Console-VX Expansion board
Webcam works through uvc driver - I have referred to this guide for driver
installation
http://wiki.gumstix.org/index.php?title=Category:How_to_-_webcams
Webcam is plugged to a usb port of the expansion board through a gender changer.
So, the deriver seems to be running (as far as I can tell), but when I plug in
webcam nothing happens.
I am trying to figure out what the problem is - any suggestions? I not even
sure if this is a software or hardware problem, so it probably would be a good
idea to try to get some other usb device to work. What is the easiest way to
check that the usb port is working?
Also, I have 4 V in the power supply instead of 5 V that I think usb needs,
could that be a problem?
Thank you,
Anton

You can use lsusb to check if your camera is being detected by the
system(that won't tell you if the device is working with the system,
though). To test the camera(ie. get a image out of it) I think you could
use mplayer...

Note: I did not test the gspca driver. I used the sonix
driver (sn9c102.ko) which is distributed with the kernel.
The latest version can be found here:

Hi,
I have a strange problem with a USB Webcam.
My setup: overo water with microSD (Last image 28fev)
Webcam: philips SPC530 + usb hub
The webcam is well install and it use uvcvideo module :
root@...:~# lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 05e3:0608 Genesys Logic, Inc. USB-2.0 4-Port HUB
Bus 001 Device 003: ID 0471:2034 Philips Webcam SPC530NC
But when I start a capture, the result is too strange. Example :
http://img717.yfrog.com/i/webcamf.jpg/
It look like if the webcam was not synchronised ? I try with cheese or my
own opencv program and I have the same problem.
Is anyone have an idea ?
Thank for all.
Bastien

Hi,
I made some test.
With the mplayer using : mplayer tv:// -tv
driver=v4l2:device=/dev/video0:width=320:height=
240 -vo fbdev -v -brightness 0 -contrast 0 -saturation 0 -flip
With the SPC530, it is impossible to change the size and it have problem in
640*480 mode.
I try with an other webcam using pwc, in 320*240 there still have problem.
But in 128*96, it is perfect.
Well is there any debit problem ? Any solution ? I need to be able to grab
some 320*240 frame.
Thank for any answer!
